Physicochenmical Foundations and Optical Parameters of the Granulation Process of NPK Fertilizers Based on Ammonium Sulfate

摘要

Physicochemical foundations of the granulation process of NPK fertilizers were studied. The effect of the composition of the starting components, type and amount of a binder, amount of the recycle, presence of a reinforcing additive in the mixture, temperature, and granulation duration on the yield and strength of the granulate was examined. The optimal parameters of the granulation of NPK fertilizers based on ammonium sulfate were determined.
